Patented Jan. 19, 1932 UNITED STATES PATENT ori-ICE BERT W. KING, FDETROIT, MICHIGAN, ASSIGNOR TO BARNES SCALE COMPANY, DETROIT, MICHIGAN,A lCORPORATION OF MICHIGAN SCALE CONSTRUCTION Application filed June 18,

This invention relates to a scale construction and it has to doparticularly with a scale of the so-called fan type wherein there is anindicator or pointer, which moves across a. chart, roughly of fan shape,with indicia thereon generally concentric with the ful# crum point oi'the moving indicator.

This invention aims to provide a Vhousing for this chart, indicator, andother associated parts which embodies a number of improvements inconstruction over housings of this character. One object of theinvention is the provision of a scale housing, and assembly embodying achart and transparent closures therefor, wherein the partsmay be veryquickly assembled or disassembled. Another object is to provide ahousing and associated assembly parts wherein the chart is substantiallyequally visible from either side thereof, so that a customer on one sideof the scale can watch the pointer or indicator and chart as well as themerchant or the like, operating the scale from the opposite side. Inthis regard, the arrangement is such that light on one side of the scalemay pass through the housing to render visible the indicia on theopposite side of the chart.

Moreover, the invention contemplates a construction wherein both thefaces of the fan-shaped housing are of uniform construction. Heretofore,such housings of fan shape have had an open face on one side and theassembly made through the open face, whereupon a flange or rim wassecured to the housing, while the other side had no fiange or rim. Inthe present instance, the arrangement is such that the several partswithin the'housing are placed therein through the top, and the housingis eventually closed by a cap or top closure member, as distinguished lfrom the flange or rim around one side of the face of the housing.

and transparent closures, one on each side of the housing.

Fig. 8 is a detail View of one of the holdng devices for a transparentclosure inem- The construction of this invention may be utilized on afan scale of any of the several types, and as shown herein, there is aVertical post or upright l, rising from the scale platform (not shown).A fan-shaped housing generally referenced 2 is secured to the top of thepost l. For this purpose, the housing rests upon the top of the post, asdepicted in Fig. 2, and the post and housing have lugs which align witheach other and through which machine screws 3 maybe taken.

This fan-shaped housing is preferably of a onefpiece constructiomsuch asa casting. .In the present instance, the walls of the houslng, as theyrise from the post 1, converge inwardly toward each other for a distanceand then diverge from each other so that the housing in the main takesthe shape of a fan. It is not essential that the walls first convergetoward each other, although the lparticular housing elected 'fordisclosure herein is so arranged. The fan-shaped faces each has afan-shaped opening therein, as clearly shown in Fig. l, and the openingsare bounded byV inwardly projecting flanges 4. The shape ofl the edgewalls and flanges of the housing is illustrated in Fig. 3, wherein theedge wall is referenced 5. Accordingly, it will be observed that bothsides ofthe fan-shaped casing, and both flanges 4 are identical, thus toido trated in Fig. 5.

i'form a uniformly shaped construction. lt will be noted that thelianges l, bounding the openings, terminate at their lower portions insubstantially parallel uall portions (S with the bottom as at 7, and thepurpose ot this construction will later be brought out.

The top ot this tan-shaped housing is open and the Walls are preferablyprovided with inwardly extending ledges or ilanges l0, for supportingcertain parts oit the assembly. The chart ll, as shown in Fig. 6, isplaced in this housing through the upper open end. This chart is securedto a suspension member 12, which may be ot angular construction, asshown in Fig. 2, and which has end extensions i3. rllhese end extensionsrest upon the ledges l0. For securing the extensions to the ledges, 'theextensions may be provided with suitable apertures as shown, and theledges l0 with screw-threaded apertures tor the reception or suitablemachine screws as shown at The chart, accordingly, hangs suspendedWithin the ian-shaped housing With its lor-.fer end freely disposed inthe hous- The chart is preferably disposed substantially centrally ofthe transverse dimensions ot the housin 'lfhe scale mechanism preterablyhas two pointers, or indicators, one as shown at l5 and the other as at'16. The chart is disposed between them. These indifators are secured toany conventional scale mechanism such as a member i7 which rocks upon a.knit-e edge bearing i8, when Weight is applied to the platform (notshown) and communicated thereto through the means ot a ribbon 19, Theusual balance Weight is shown at 20. 5

it desirable to have a support for the lower end of the chart, and torthis purpose, a screw-threaded member 2l is provided (Fig. 23), which issecured to the chart as by means ol' a bracket L52 and bolt 23. Each endot the member 2l is screiv-threaded, and each has thereon an adjustingnut Q-i. These ad- `iusting nuts are retracted upon the bolt member 2lwhen the chart is assembled or placed within the housing, and then thenuts 2d may be turned on the screw-threads so that they move outwardlyand engage the interior Walls oit the i'ianges By making properadjustments, the chart can be adjusted as to its position and held insuch position.

llhe manner in which the chart is placed Within the housing is depictedin Fig. 5, wherein the chart is shown as being partly ,'ithin thehousing. hiita-ble transparent closure meml'iers are used to close theopenings at the opposite tacos oi the 'tan-shaped housing, rlheseclosure members preferably being glass panels 2. The glass panels are oia shape which corresponds to the shape of the housing and are placed inthe housing by insertion through the top thereoit', as illus- The upperends are spaced apart by means of a suitable spacing element which maybe in the torni ot a channel-shaped member 2G, carried by the suspensionmember l2 tor the chart.

rlhe lower ends ot the glass panels may be held in place by removableclip members rllhe body portions oll these clip members 2i' are such asto generally correspoml to the shape of and close the lower portion ofthe openings del'ned by the walls (i and T. The clips have suitableprojections 28, and also carry a casing engaging member ln securing aclip to the housing, the same is placed in proper position as regardsthe housing at a suiicient height 'trom the lower wall 7 ot the openingor the housing as to permit the clip member 2S) to pass through theopening, whereupon the clip member is urged downwardly until the lugs,or projections, Q8 come into Contact with the wall At this time, thehousing engaging member 2f locks behind the adjacent portions oli theflanges 4e (Fig. i). rlhe louer edges or' the glass panels are receivedby the engaging members and rest thereon, these members being proi'ierlyshaped in cross section tor this purpose, as illustrated in Fig.

A closure member is provided :lor the upper end et the housing, and itmay be in the 'lorm of a cap 30 which lits over the upper end ol thehousing. lt may be secined in place by means of machine screws takentlierethrough, such screws being shown at fl, and threaded intoscrew-threaded openings in the ledges 10.

The assembly oi the parts Within the housing can be very quickly made,or the parts can be very quickly removed tor any adjustment or repairpurposes. In making the assembly, it is preferable to lirst place thechart in position, the glass panelsy being not yet in place, so that anoperator may adjust the transverse supporing member ilor the lower edgeoit' the chart. rlhe glass panel supportiuM` clips 2? ma)v nonY besnapped into place, and then the panels inserted through the top of thehousing', atter the manner illustrated in Fig. 5, 'whereupon the topclosure or cap secured in place. The parts ot course, may be easilyremoved by' a reversal. oi? this procedure.

lt is to be noted that the chart is ot such a size that its divergingedges 35 are spaced .trom the side walls 5 of the housing. thus .iprovide a space "f Also the chart is ifnelfer- (n). ably positionedsubstantially centrally as regards the trzinsverse dimension ot theheus` ing. rthe chart substantially equally visible from e'v 1er side oithe housing through the resilientL 'e glass panels. ln the event thatthe majority olf the illuminating light comes .from one side oit thehousing, a ce 1.'. amount of light is permitted to pass through theopenings 3G in such a manner as to ade- (ipiately illuminate, or to makezulequately visible the opposite side o i the chart. lu

scales heretofore known, it oftimes was the case that one side of thechart, usually that of the customer, was not sufficiently visible, eX-cept by artificial light. lith this invention, artificial light is notrequisite, although it may be provided if desirable. Of course, thelight coming from one side of the scale does not pass directly throughspaces 36, inasmuch as such spaces are covered by ianges 4, but asufficient amount of light is reflected in such a manner as toadequately light up theopposite face of the chart.
